Monkeyfacegrace, I think you'll find I said don't be a bitch, as in, don't say mean things; in this context, things that are provocatively harsh for the sake of it.
The words I didn't put in your mouth were:
"Forgot to add, if you act like this, next time he may not come home. He may pass out somewhere random and be in danger as he is worried about the consequences of coming home."
Huge emotional load there, considering that the other words I didn't put in your mouth were:
"This is ridiculous. He is 21, and has every right to get drunk."
So, she was being ridiculous to react to him being drunk, but shouldn't share her concern because if she act[s] like this, next time he may not come home.
Yes, telling your kid off for his 'right' to get drunk and roll in to your shared home in an utter state is completely U, an infringement of his adulthood. Yet, said adulthood is unlikely to prevent him becoming so afraid to come home that he would be likely to face mortal peril?
I can't abide it when people prey on motherly fears about their children lying in a ditch somewhere to make a point. In this case, as I posted, I also feel it rather contradicted your initial position.
